我正在使用Jenkins v2.73.2并希望使用管道脚本功能将String参数从一个作业（TEST_JOB）传递到另一个作业（BUILD_JOB）。通过安装“参数化触发插件”，作业1（上游作业）＆gt;我理解同样如下所述在没有管道的情况下完成。构建后的操作＆gt;选择“在其他项目上触发参数化构建” 在下游作业中：要访问此参数，我们使用$（参数名称）。
我希望使用Pipeline完成同样的工作。通过googing我找到了一些eaxmples并基于它我已经创建了这种方式，但得到以下错误消息

Finished: FAILURE
第一份工作：（TEST_JOB） -
node('Jenkins_1') {
stage ('Build') {
build job: 'BUILD_JOB', parameters: [$class: 'StringParameterValue',name: 'BRANCH_BUILD', value: "${params.BRANCH}")]
}
}
注意：在这里，我想将params.BRANCH值传递给第二个作业（BUILD_JOB）
第二份工作：BUILD_JOB -
node('Jenkins_1') {
deleteDir()
stage 'Checkout'
git (url: 'ssh://git@source.mmr:7000/demo.git',
credentialsId: 'XXXXXX',
branch: '${BRANCH_BUILD}')
stage 'Build'
bat 'call "C:\\Program Files \\MSBuild\\12.0\\MSBuild.exe" sample.sln /t:Rebuild /p:Configuration=Release'
stage 'Archive'
echo 'Archive'
}
答案 0 :(得分：0)
您为参数传递的值是多少？另请尝试更改参数的名称。我猜它正试图设置一些Jenkins的内部变量，因为参数名称与它匹配。所以请重命名参数，然后重试。
答案 1 :(得分：0)
在BUILD_JOB中，使用
branch: "${params.BRANCH_BUILD}".
请注意，我做了两处更改 - 我使用了双引号并添加了params作为传递参数的前缀。
